Linfo IP v. Shop LC Global: Voluntary Dismissal With Prejudice After 345 Days
Linfo IP, LLC asserted US9092428B1 — covering systems and methods for information discovery in text content — against online retailer Shop LC Global, Inc. in the Western District of Texas. The plaintiff voluntarily dismissed all claims with prejudice under Rule 41(a)(1)(A)(i) before the defendant had answered, with each party bearing its own costs. The case closed 345 days after filing without any merits adjudication.
Plaintiff exits with prejudice before defendant files a single pleading
On June 12, 2023, Linfo IP, LLC — a patent assertion entity represented by Ramey LLP — filed suit against Shop LC Global, Inc. in the Western District of Texas before Judge Alan D. Albright, asserting infringement of US9092428B1. The patent, filed under application number US13/709827, covers systems, methods, and user interfaces for discovering and presenting information in text content, a technology area with broad relevance to e-commerce product discovery and content recommendation platforms.
The case closed on May 22, 2024, when Linfo IP filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i), which permits a plaintiff to dismiss without a court order provided the defendant has not yet answered or filed a motion for summary judgment. Critically, the plaintiff elected to make the dismissal with prejudice as to the asserted patent — a self-imposed, more restrictive outcome than the without-prejudice default that Rule 41(a)(1) would ordinarily provide. Each party was designated to bear its own legal costs.
A dismissal with prejudice entered before the defendant has answered is commercially significant: it permanently extinguishes Linfo IP’s ability to assert US9092428B1 against Shop LC Global in any future proceeding. The 345-day duration suggests negotiations or licensing discussions may have occurred off the record, though the public filing is silent on any settlement terms. The decision to accept a prejudicial dismissal rather than pursue litigation to a merits ruling is consistent with a resolution that provided Linfo IP with sufficient commercial justification to foreclose future claims voluntarily.

Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to dismiss before answer
Federal Rule 41(a)(1)(A)(i) allows a plaintiff to voluntarily dismiss without a court order if the defendant has not yet served an answer or a motion for summary judgment. Here, Linfo IP invoked this right but upgraded the dismissal to with prejudice — a unilateral election that goes beyond the rule’s default. No judicial approval was required, but the with-prejudice designation carries the same preclusive force as a court-ordered judgment on the merits.
Procedural — pre-answer dismissalLinfo IP surrenders future claims against Shop LC on this patent
By stipulating with prejudice, Linfo IP permanently relinquishes the right to reassert US9092428B1 against Shop LC Global. This is a meaningful concession: most patent plaintiffs who dismiss under Rule 41 do so without prejudice to preserve optionality. The with-prejudice election here strongly suggests a negotiated resolution — potentially a paid license or settlement — provided the commercial incentive to close the matter permanently, though the public record does not confirm this.
Claims extinguished as to this defendantShop LC Global secures permanent protection from this patent claim
Shop LC Global obtains the functional equivalent of a judgment in its favour without incurring the cost or risk of full litigation. The with-prejudice dismissal creates a preclusion bar: Linfo IP cannot re-file on US9092428B1 against this defendant. The cost-bearing arrangement — each party its own fees — means Shop LC Global absorbed its own legal costs but faces no further exposure on this patent from this plaintiff. Defendant counsel from Gillam & Smith LLP and Hawkinson Yang LLP navigated the case to a clean exit.
Permanent bar — no re-filing riskPatent remains live against other defendants in the e-commerce sector
The dismissal with prejudice is defendant-specific. US9092428B1 remains an active, enforceable patent against all other parties. E-commerce platforms and content discovery technology vendors with similar text-based product recommendation or information presentation systems should note that Linfo IP retains full enforcement rights. The Western District of Texas — Judge Albright’s court — remains a preferred venue for patent plaintiffs, and the patent has not been invalidated or narrowed by any court ruling in this proceeding.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) precisely and confirms the defendant had not yet answered — preserving the plaintiff’s unilateral right to exit. The explicit with-prejudice designation is legally significant: it transforms a procedural withdrawal into a permanent bar with the preclusive force of a final judgment on the merits as between these parties. The each-party-bears-own-costs clause forecloses any fee-shifting claim under 35 U.S.C. § 285. No court order was required, and no merits finding was made on validity, infringement, or enforceability of US9092428B1.
US9092428B1 — System and methods for information discovery in text content
US9092428B1, filed under application number US13/709827, protects systems, methods, and user interfaces directed at discovering and presenting information embedded within or derived from text content. This technology domain sits at the intersection of natural language processing, content recommendation, and user interface design — capabilities that underpin product discovery engines, in-article linking systems, and contextual recommendation layers widely deployed by e-commerce and digital media platforms. The patent’s grant as a utility patent with a B1 designation indicates no pre-grant publication, consistent with an application that issued without prior publication.
For the e-commerce sector, US9092428B1 represents a category of IP that touches core commercial functionality: the ability to surface and present relevant product or content information to users navigating text-heavy pages. Online retailers, content platforms, and SaaS vendors offering recommendation or content enrichment tools face the broadest exposure. The patent remains fully enforceable following this dismissal — no claim was cancelled, narrowed, or found invalid — making it a live risk for any company whose product architecture involves automated information discovery and presentation from text inputs.
Should your product team run an FTO against US9092428B1?
Any company building or deploying systems that automatically identify, extract, or surface information from text content for user presentation should evaluate exposure to US9092428B1. This includes e-commerce platforms with contextual recommendation engines, digital publishers using in-text linking or content discovery widgets, and SaaS providers offering NLP-driven product tagging or search suggestion tools. The fact that Linfo IP has already pursued one defendant in this space — and secured a with-prejudice exit consistent with licensing resolution — suggests an active enforcement programme that may target other market participants.

Cases involving information discovery and content presentation patents litigated before Judge Albright in the Western District of Texas follow distinct resolution patterns worth benchmarking.
What this case signals for the text content discovery IP landscape
A with-prejudice exit before answer is a rare pattern that typically signals off-record resolution — and leaves the patent fully armed against the broader market.
With-prejudice voluntary dismissals are statistically rare and commercially significant
Most Rule 41(a)(1) dismissals default to without prejudice. A plaintiff who voluntarily elects with-prejudice treatment before the defendant has even answered is signalling a definitive end to this dispute — typically because something of value has already changed hands. Companies operating in adjacent technology spaces should treat this pattern as evidence of an active licensing programme around US9092428B1.
